1. ME3000SP Introduction
ME3000SP is an AC coupled bi-directional battery converter. Customers can purchase batteries & ME3000SP as an energy storage add-on to his/her existing renewable energy system. ME3000SP helps to achieve optimal usage of renewable energy. ME3000SP controls bi-directional flow of electric power, work under auto or time-of-use (TOU) modes, charge / discharge the battery when needed.
In auto mode, ME3000SP will charge surplus renewable energy into the battery & discharge battery to supply power to local load when renewable energy is not enough.

2. Safety Notes
Before installation, please make sure you read & understand this manual. ME3000SP strictly comply with safety rules of design and testing. During the installation, operation and maintenance, operators should abide by local safety regulations. Improper operation may cause an electric shock or damage the equipment and properties.
2.1 Safety Notes
Electrical installation and maintenance must be carried out by competent electricians according to local regulations.
ME3000SP can only be installed by qualified electrician, and only those who have appropriate accreditation, as required by local authority.
Do NOT put explosives or flammable materials, e.g. gasoline, kerosene, oil, wood slab, cotton, or rag close to batteries / ME3000SP.
Disconnect DC (battery) & AC (grid & load) first, then wait at least 5 minutes (discharge capacitors) before maintenance to prevent electric shock.
ME3000SP shall be disconnected completely (DC & AC) while being maintained.
ME3000SP can be very hot while working. Switch off ME3000SP & wait ME3000SP to cool down before maintenance.
Keep children away from batteries & ME3000SP.
It’s not allowed to open the front cover of ME3000SP. This will void the product warranty.
ME3000SP damaged by improper installation/operation is not covered by the product warranty.
2.2 Installation and Maintenance Notes
The battery has been ~ 60% charged before being delivered and shall be prevented from short circuit during transportation and installation.
ME3000SP/batteries shall be placed in a well-ventilated place. Do not put the ME3000SP/batteries in an airtight or badly ventilated place or cabinet. This can be very harmful to system performance & system service life.
Keep ME3000SP/batteries away from direct sunshine. Don’t put ME3000SP/batteries close to a furnace or fire.

If electricity is more expensive in high demand time (peak rate) & electricity is much cheaper in low demand time (off-peak rate).
You can select an off-peak period to charge your battery. Outside the off-peak charge period, ME3000SP is working in Auto Mode.
If your family normally go to work/school on weekdays & stay at home on weekends, which means the home electricity consumption is much higher on weekends. Thus, you need to store some cheap electricity on weekends only. This is possible using our Time-of-use mode.
In summer, if your PV system can produce more electricity than your home electricity consumption. Then you don’t need to set an off-peak charge period to charge your battery in summer at all. You can select an effective date (normally winter) for Time-of-use mode in this case. Outside the effective date, ME3000SP is working in Auto Mode.
You can set multiple Time-of-use rules to meet your more complex requirement. Right now we support 4 rules maximum (rule 0/1/2/3).

Step 2 Press the SD card and take it out. Insert the SD card into a micro-SD card reader, then insert micro-SD card reader into a PC; (NOTE: micro-SD card reader & PC are not provided by SOFARSOLAR).
Step 3 Format the SD card. Copy the “ES3000firmware” folder to the SD card.
Step 4 Insert the SD card back to the SD card slot.
Step 5 Then turn on DC isolator (battery), wait 5 seconds, turn ON AC circuit breaker (grid), press “Back” to enter main menu. Press “Down” to select “4. Software Update”, then press “Ok”.
Step 6 “input password” is shown. Input the password (“0715”), press “Up” or “Down” to change the 1st digit, press “OK” to switch to next digit, when “0715” is shown on the screen, press “Ok” to start firmware update.
Step 7 After finishing firmware upgrade, turn OFF AC circuit breaker (grid) and DC isolator (battery), lock the communication waterproof cover with four screws, then turn ON DC isolator (battery), wait 5 seconds, turn ON AC circuit breaker (grid), ME 3000SP will start to operate automatically.
NOTE: If “DSP communicate fail”, “Update DSP1 Fail” of “Update DSP2 Fail” is shown on the screen, which means the firmware upgrade is unsuccessful, please turn OFF AC circuit breaker (grid) and DC isolator (battery), wait 5 minutes, then start again from “Step 5”

8. Troubleshooting Code Name description solution
ID01 GridOVP The power grid voltage is too high If the alarm occurs occasionally, the possible cause is that the electric grid is abnormal occasionally. ME3000SP automatically returns to normal operating status when the electric grid’s back to normal.
If the alarm occurs frequently, check whether the grid voltage/frequency is within the acceptable range. If no, contact SOFAR technical support. If yes, check the AC circuit breaker and AC wiring of the ME3000SP.
If the grid voltage/frequency is within the acceptable range and AC wiring is correct, while the alarm occurs repeatedly, contact SOFAR technical support to change the grid over-voltage, under-voltage, over-frequency, under-frequency protection points after obtaining approval from the local electrical grid operator.
If you confirm that AC wiring is correct & grid voltage/frequency is within acceptable range, the alarm still occurs repeatedly, try to change country code to 22. Then restart ME3000SP to see if problem is solved.
ID02 GridUVP The power grid voltage is too low
ID03 GridOFP The power grid frequency is too high
ID04 GridUFP The power grid frequency is too low
ID05 BatOVP The battery voltage is too high
